I've applied the DT patches now (branch: v4.12/dt64)

This is fine once the ranges have been applied to the device trees I guess.

Tell me when you want me to merge this.

Hi Linus,

Kevin should merge the DT patches since they have now Tested and Reviewed by's, 
so you can merge it now if you can.
Since it will live in you pinctrl tree, it will only impact linux-next until 
Kevin merges them.

Thanks,
Neil

did you mean devicetree or DT instead of "DR"?

[RFT PATCH 5/6] pinctrl: meson: use gpio-ranges from DT

2017-03-23 Thread Neil Armstrong
When trying to add a gpio-hog, we enter a weird loop where the gpio-ranges
is needed when gpiochip_add_data() is called but in the current implementation
the ranges are added from the driver afterwards.

A simple solution is to rely on the DR gpio-ranges attribute and remove the
call to gpiochip_add_pin_range().
